The can holds 160 kg of kerosene. What amount of heat will be released during the complete combustion of this kerosene? Its calorific value is 46 MJ / kg
The amount of heat that is released during the complete combustion of kerosene from the can is calculated using the following formula:
Q = q * m, where q is the specific heat of combustion of kerosene (according to the condition of the problem q = 46 MJ = 46 * 10 ^ 6 J / kg), m is the mass of kerosene in a can (according to the condition m = 160 kg).
Let’s do the calculation:
Q = 46 * 10 ^ 6 * 160 = 7360 * 10 ^ 6 J = 7.36 * 10 ^ 9 J = 7.36 GJ.
Answer: With the complete combustion of kerosene, 7.36 GJ of heat will be released from the can.
